Bc it known that l, WILLIAM M. Kunnen, of C hiw cago, in the county of Cook andState of Illinois, have invented an `Improved Lock; 'and I"do hereby declare that the followingis a full and exact description thereof',`which will enable those` skilled in the art to'inake i, and use the same, reference being hadto the accom- 1 panying drawing and letters marked thereon making part of this specification, in which Figui-e1 is a perspective representation of my inrvention. i

Figure 2,'an inverted perspective view'of the catch, which is attached to the lid of a box cr'trnnk.

"Figure 3, a transverse section of the lock through `oneot` the two tumblers and key-bolt. 4 "lhe nature of the present invention consists in the peculiar form of the key-bolts, they being hollow to receive the needle-key for opening the spring catches, as `the, whole is hereinafter `fully described. 4

` A A represent the case of` the lock, which is made l of metal, or other suitable material, in the usual man@ ner. i

`1n this case A'A is formed a bearing for one or more key-bolts, C, and to these key-bolts are fastened tuniblers B, which may be turned on said bolts and fastehed b'y\me ans of nuts J, so that the sharp edges K fof `the key-bolts may have any given position relative to cach other as the operator may desire, while at the same time the slots in the tumblers are 'set for unlocking the catch, the setting of the bolts being indicated,

door or drawer, as the case may be, 'to suit the convenience of those who use the lock.

The tumblcrs B are provided with anges I on both vnotches S in the tumblcrs must be brought direct-ly opposite the catches D when the lock is-to' open or shut, and that, by turning'the tumblers ou the bolt i C by means of the nuts J, the combination is changed.

i -In order to provide a spring lock, a spring catch, G, figs. 2 and 3, is fastened to the back part A of the case, and it locks over the plate F, and, consequently, holds it fast to the 'case A A.

. To enable the `spring G to be opened from the outside of the lock, the bolts C `are made tubular, so that a needle-key, H, may be pnt through them and push the spring back, as shown in iig. 3.

In fitting the lock to a drawer or door, suitable keyholes should be made for the bolts C, as is-usually` Y done in such cases.

Having thus described my invention, f

XVhat I claim, and desire to secure by Letters Pat-V key-bolts G, catch-plate F, and needle-key Il, as and for the purpose specified,
